Embodiment Construction

[0015] The present invention will be further described below in conjunction with embodiment.

[0016] Low-emission and low-smoke density natural fiber modified PVC green facing composite material, which is a multi-layer composite structure, including a wear-resistant layer from top to bottom, a color film layer, a base material, and a negative film; the base material and the negative film are hot-pressed together The wear-resistant layer is a transparent film with a UV coating on the outer surface; natural fibers such as wood powder and straw are added to the base material.

[0017] The natural fibers such as wood flour and straw are pretreated through a surface composite treatment process (ethylene glycol / coupling).

[0018] The wear-resistant layer is composed of carbon nanotubes (CNTs) grafted with methyl methacrylate (MMA) on the outer surface, and nano-TiO 2 Transparent film coated with modified epoxy acrylic resin.

[0019] During the heat-pressing process of the base ...

Abstract

The invention discloses a low-emission and low-smoke density natural fiber modified PVC green facing composite material. The composite material comprises a wearing layer, a color film layer, a base material and a substrate from top to bottom; the base material and the substrate are hot-pressed; the wearing layer is a transparent film with the external surface containing a UV coating; wood powder, straws and other natural fibers are added to the base material; the wood powder, straws and other natural fibers are treated through a surface composite treatment technology; the wear layer is a transparent film, and the external surface of the transparent film contains carbon nanotubes with the surface grafted with methyl methacrylate and a nano-TiO2 modified epoxy acrylic resin coating with the surface being hydrophobically modified; and a group of synergistic low-molecular expelling agents is adopted in the hot-pressing process of the base material and the substrate, and a device with a specially reconstructed structure is combined, so organic volatile components are maximally removed from the blend composite material in a molten state. The composite material has the characteristics of good antistatic and antibacterial functions, low cost and environmental protection.

Description

technical field [0001] The invention relates to a PVC composite material, in particular, the invention relates to a natural fiber modified PVC composite material. Background technique [0002] Natural fiber has the characteristics of rich sources, renewable, degradable, high specific performance, etc. Natural fiber / PVC composite material is a new type of green and environmentally friendly composite material, which can be used for large-scale utilization of crop straw, reduce environmental pollution, and reduce environmental pollution. Both wood consumption and recycling of waste plastics are of great significance. Foreign research in this area was earlier, and the products have been widely used, while domestic research started late, and there is a big gap between the technical level of natural fiber / PVC composite materials in my country and the international advanced level. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present inventi...
